Bestech Australia presents the dV-2 PS pressure switch, from Keller. This model is a digital manometer with two independent pressure switch outputs. The gauge employs microprocessor technology which produces highly accurate results. All readings are linearised and temperature corrected, to give an accuracy of 0.1% FS.
There are two independent switches for High and Low control functions. These are solid state and therefore not subject to wear. The switch points are programmed directly from the two front panel buttons and a menu system. Alternatively this pressure switch can be connected via the RS485 link to a computer, and configured using the “Pressure Switch Console” software. User defined configurations can be stored on the computer for future reference.
Two independent floating switches are available. Neither is subject to wear and they can be operated individually as make or break contacts. The switch can provide a window function or be utilised as a hysteresis switch. These switching functions enable the dV-2 PS pressure switch to assume control tasks. Respective switch output status is displayed on an LED located on the front.
The zero point on the pressure switch can be changed with the zero function, and max/min values can be reset at any time. The pressure can be displayed in bar, MPa or PSI. Pressure ranges are available from 0-4 bar to 0-700 bar, and accuracy is 0.1% FS, which includes linearity, repeatability, hysteresis and temperature error. Switch delay is 30ms, while temperature range is 10-40°C. Protection is to a rating of IP64.
This pressure switch is available in Australia and New Zealand from Bestech Australia .
